NVIDIA is reportedly preparing a new Blackwell chip for China, called the B30A, which will replace the Hopper-based H20 & offer faster performance.
NVIDIA's Blackwell B30A Chip To Be H20 Replacement For China, Offering Half The Performance of Blackwell Ultra B300
According to Reuters, it is reported that NVIDIA might have finalized a new Blackwell chip design for China that is compliant with US regulations. The new chip, presumably called the B30A, will be faster than the existing Hopper-based H20 option but feature vastly lower performance than the top-tier Blackwell chips, such as the B200 and the upcoming B300.
As per the information, the NVIDIA Blackwell B30A GPU will feature a single-chip design, so it won't come with the dual-chiplets that will be featured on the standard Blackwell B200/B300 offerings. For reference, the NVIDIA Blackwell Ultra B300 solution will pack 50% more performance than Blackwell B200, 50% more memory, and twice the interconnect speeds. The top SKU will comprise two reticle-sized GPUs with a total of 15 PetaFLOPs FP4 compute and up to 288 GB HBM3e memory.
The new chip, tentatively known as the B30A, will use a single-die design that is likely to deliver half the raw computing power of the more sophisticated dual-die configuration in Nvidia's flagship B300 accelerator card, the sources said.
A single-die design is when all the main parts of an integrated circuit are made on one continuous piece of silicon rather than split across multiple dies.
The new chip would have high-bandwidth memory and Nvidia's NVLink technology for fast data transmission between processors, features that are also in the H20 - a chip based on the company's older Hopper architecture.
If NVIDIA's B30A is going to be half the spec of the B300 chip, we can expect up to 144 GB of HBM3e memory, which will be an improvement over the H20's 96 GB memory, but that chip also featured 41% fewer cores and 28% lower performance than the Hopper H100 configuration.
It is stated that NVIDIA hasn't finalized the specifications, but the company is planning to deliver the first samples of the B30A Blackwell chip to a China-based client as early as next month. Early reports suggest that there's a big demand for the B30A chip in China ahead of its launch.
US President Donald Trump has also hinted that there will be an unenhanced or a castrated version of Blackwell for China. He also said that he will be talking with Jensen, so a deal could go through if there's a 15-20% tariff on the said chips for China. Following is the full quote:
And Jensen also has a new chip, the Blackwell. You know what the Blackwell is? The Blackwell is Super Duper Advanced. I wouldn't make a deal with that, although, it's possible i'd make a deal a somewhat enhanced, in a negative way, Blackwell.
In other words, take 30% to 50% off of it. But that's the latest and greatest in the world. Nobody has it, they won't have it for five years. But the H20 is obsolete. You know it's one of those things but it still has a market. So I said, I want 20% if I am going to approve this for you, for the country, for our country, for the US. I don't want it myself. You know, every time I say like 747, I want, I want, for the Air Force. So when I say I want 20, I want for the country. I only care about the country, I don't care about myself. And he said would you make it 15. So we negoitate a little deal.
So he's selling an essentially old chip that Huawei has a similar chip, a chip that does the same thing. And I said if I am going to give it to you because they have a stopper, what we call a stopper, not allowed to do it, restricted, it's really known as a restrictive covenant, and I said If I'm going to do that , I want you to pay us, a country, something, I am giving you a release, I release them only from the H20.
Now, on the Blackwell, I think he's coming to see me again about that but that will be an unenhanced version of the big one.

So it looks like B30A will be the Blackwell chip that will be given to China in the coming months. It will be interesting to see what sort of specifications are finalized and where it lands when compared to the true chip.
